I found a pretty curious post about home automation project that I want to show you. Nothing better than the words from the author about this project to know it:
I recently presented a project with the Raspberry Pi in college where I study Computer Science.
The goal was pretty generic and was used GPIO pin header that brings the Raspberry Pi and to control the I/O from a mobile device.
So for this project I thought of making a model of a home and simulate home automation.
